Short story is that since updating from 4.13 to 4.15 I get slow_requests in Ceph with only low load on Ceph. If I boot back, those
are gone.

Or at least almost as I was able to produce slow_requests with 4.13 but only if deep scrubing was manually initiated on all PGs.


Sage Weil (Ceph dev) suggested that this probably is MTU or bonding related and thus I'm currently testing with different
settings. Another guy on the ceph-devel list suggested different driver versions so I was checking that as well.



Long story is here:
